I believe it has already been pointed out that she was criticising others for working as an MP as a second, third or even 12th Job. Rayner is working as an MP. She has joined an agency to do a tiny bit of extra work out of hours.
Compare that to your hero Farage who hasn't even held a Constituency Clinic in his Constituency of Clacton. His Constituents can't speak to him. In his first year he spoke in Parliament just 45 times. He voted 91 times and missed many key votes. He made 9 trips abroad during his first year, and on holiday during parliamentary time. He has failed to register his interests, his properties and his boat.
